Having tried all three, its a stark difference in how much more social Lemmy is comparatively. Its not even close. Almost all posts I've encountered on lemmy have interaction; whereas, more often than not, posts on the other two platforms have no interaction. Wonder what the driving factor is behind this difference?
I assume because people follow topics on lemmy, unlike microblogging where people have to follow each other to interact (one-to-many vs one-to-one). So it’s easier to interact with many people that you don’t necessarily had to be following prior, which increases the chances of interacting with more people.
you can follow hashtags. I follow #opensource and a few other interests and I've found some interesting stuff you don't generally see in other places. but yes, the format is completely different and I find lemmy allows for better discussion than Mastodon.
Yeah Mastodon seems way less about discussion and way more about surfacing cool shit you wouldn't otherwise see.
